It was a costly game for the Ravens' offense and special teams Thusday night sustaining damaging losses in terms of injuries as two key players left the game nursing ailments.
First Pro Bowl kick returner Jacoby Jones sprained his knee in the second quarter; he didn't return.
Jones indicated he'll undergo a magnetic resonance imaging exam Friday.
"I don't know" Jones said when asked how long he thinks he'll be sidelined. "I got to find out."
On a punt return Ravens rookie safety Brynden Trawick with his head down in his first NFL game barreled into Jones as he signaled for a fair catch. Both players were shaken up on the play and left the field slowly.
"I didn't see it" Jones said. "I had my eyes on the ball."
"I just didn't see him" Trawick said. "It was bad on my part. There's not much I can say for real."
Once Jones got to the sideline his knee was immediately examined by team doctor Leigh-Ann Curl.
Later in the quarter starting right offensive tackle Michael Oher sprained his ankle; he didn't return either. Oher was replaced at right tackle by rookie Rick Wagner a fifth-round draft pick from Wisconsin.
Wagner allowed a sack in the third quarter by Broncos outside linebacker Shaun Phillips.
The Ravens are now precariously thin along the offensive line. The only other active offensive lineman was backup center A.Q. Shipley with guard Jah Reid a healthy scratch.
Oher didn't appear to be seriously hurt and was able to limp off the field under his own power and wasn't in a walking boot or crutches afterward.
"I have to see how the next couple of days go" Oher said. "Hopefully I'll be all right though."
